The EK 428 SROZ is a durable 428-size O-ring drive chain designed for motorcycles, ATVs, and other powersports applications requiring dependable chain performance. This 136-link chain uses heat-treated steel alloy construction to provide reliable strength and long service life under everyday riding conditions. Its value-focused design delivers durable performance without compromising the quality expected from EK products.
O-ring seals help retain lubricant inside the chain joints while helping prevent grit and other contaminants from entering. This reduces wear on the pins and bushings and supports smoother, more consistent power transfer. The EK 428 SROZ-136 is supplied with a semi-press-fit clip connecting link for installation and chain adjustment according to the vehicle manufacturer’s service requirements.
Designed for fitment with compatible 428 chain drive systems, this EK chain is suitable for replacement applications where the original equipment chain uses the same size and link count. Verify the motorcycle or ATV model, sprocket configuration, chain size, and required link count before installation. The manufacturer part number and vendor part number are both 428SROZ-136.
